Hi crack_x01
See topic http://www.plc.net.ru/viewtopic.php?t=6 ... hlight=pid

and for this application use heat - cool PID function block algoritm,(three-step control mode Page 2-95 of Modular PID Control Manual). or can make this same application with ABB commander C355 Process controller for a cheaper price.
